The elevation model allows for example simulation of receiving, coverage and service areas. It can also be used for mass calculation of excavated material and landfill and for calculating inclinations, steepness or profiles. Application areas are found, for example in geology, geography and forestry.

The product is updated once a month if the data in the Elevation model 2 m product has changed.

The product is available from the NLS MapSite's Download geospatial data -section according to the above-described updating rhythm.

Mention the name of the Licensor (the National Land Survey of Finland), the name of the dataset(s) and the time when the National Land Survey has delivered the dataset(s) (e.g.: contains data from the National Land Survey of Finland Topographic Database 06/2014).

The elevation accuracy of the product is 1.4 m on average (1.4 m in 95% of the cases and 2 m in 99% of the cases). In the ASCII version the elevation data is expressed in metres (three decimals, e.g. 42.604) and in the GeoTiff version as float values in metres (only the first three decimals are significant). In both versions, objects below sea level have a negative value.

Elevation model 10 m has been derived from Elevation model 2 m in those areas covered by the 2 m model. In other areas, Elevation model 10 m has been produced of contour lines made more accurate in connection with the regular maintenance procedures of the Topographical database, of ground surface points digitised in a stereo workstation environment and of all the objects in the Topographical database with a z-coordinate. In these areas, the elevation accuracy of the product is 1.4m on average (1.4 m in 95% of the cases and 2 m in 99% of the cases). In areas derived from the 2 m model the locational elevation accuracy and details are considerably better.

Elevation model 10 m depicts the height of the terrain above sea level. The height values are in accordance with the system N2000.
